Anna Mackenzie, born on the sign of Scorpio, is a smart and well-meaning college student who displays great determination as a team player and a loyal friend. Standing at 5'9" feet and weighing 160 lbs with a athletic build, wearing a skyblue tanktop with red capri pants, Anna has aqua-colored eyes and long flowing golden blonde hair. Anna also has an avid interest in sea exploration which inspired her into taking marine biology as her college major. She participated in an experiment that gave her abilities that include turning her body into a liquid form and returning to her solid bodily form at will, using her powers to protect land and sea alike from criminals.
Amphibious in nature with ability to convert her body mass to living water, Aquamarine's enhanced physiology allows her to withstand underwater pressure temperature with superhuman speed and agility. She can also manipulate water in various way from cutting metal to propelling herself and detect any immediate threat within a 20 yard radius. While practically invincible in the water, the only setbacks Anna deals with are requiring periodic re-hydrations and having a grave disadvantage in very dry environments.
